Sorry for the long radio silence.

I just got around to doing this and I found that there are some
configs that are desirable to have when running KUnit under x86 in a
VM, but not UML. So should we have one that goes in with
config-fragments and others that go into architectures? Another idea,
it would be nice to have a KUnit config that runs all known tests
(this probably won't work in practice once we start testing mutually
exclusive things or things with lots of ifdeffery, but it probably
something we should try to maintain as best as we can?); this probably
shouldn't go in with the fragments, right?

I will be sending another revision out soon, but I figured I might be
able to catch you before I did so.
